IMPROVBD TIRE-BENDING- MACHINE.

The Schedule referred to in these Letters Patent and making part c! Lixo came.

To all whom lit may concern.-

Be. it known that I, JOHN NAUGLE, of Mooresville, in the county ot"1\Iorgan, and State ofl Indiana, have inrentcd'certain new and useful Improvements in Ilre-leuling Machines, of which the thllowing is a tull, clear, and exact-description, reference being had to the accompanying drawings, which make part ot' this speciticatiou, and in which- Figure 1 represents a plan or top view of my improved tire-bending machine, and

Figure. 2, a side elevation of the same.

The object ot' my invention' is to provide a simple aud elcient tire-bending machine, by the use of which lateral twisting of the tire shall be obriatcd, and twisted tires straightened, as well asto afford convenient means i'or the insertion, binding, and removal ot'thc tire; to which ends, I mount two rollers in bearings in a suitable frame, and athird roller upon a movable carriage.

Each iioller is ,provided with a pair of collars set at a proper distance apart to suit the width ot' the tire, grooves being cut upon the rollers, within and adjacent to the collars, to admit the frayed edges of the tire'.

The collars are placed upon' the rollers, in 4such position, that when in operation, the three pairs shall be truly in line, thereby preventing any lateral twist being imparted to the tire. y

One end of the centre roller issupported, when the machine is not in operation, upon a. -pivoted latch, which cau be swung aside to admit or remove a tire when welded up, thus enabling the machine to be used for tiuishing or straightening imperfect ortwisted tires. l

1n the accompanying drawings, which show a convenient arrangement of parts for cairying'out the objects ot' my invention A represents the iiame ot the machine, and

AB and C, rollers, which rest in bearings therein.

third roller, D, is mounted in bearings `in a movable carriage, F, which slides on ways `upon -the frames.

The cent-re roller B moves in bearings in an arched support, I, attached to the iame, one of its ends being supported, when not in operation, upon a pivoted 4latel1,-H, on the frame, which rests on a pin, h, ou

the support.

This latch can be swung aside at pleasure to admit of the insertion or removal 0i' tire.

The distances ot' the rollers vB and I) from the centreroller can be varied, to suitdit'erent eurvatnrcs, by means ofthe series of bearings b 'b in the frame A and carriage F. v

Each roher is proridrd with a pair ot' collars, E E, set at such a distance apart as wilt admit a. tire, ot' the width required, difierent rollers heilig necessary for dit-ferent widths of tire.

The collars are tixed upon the rollers in such position that vthe three pairs shall be truly in line when the machine is in operation, by which means all liability to lateral twistiugot the tire 'is obViated, and the machine rendered adaptable to `straightening twisted tires.

Grooves c c are formed upon the rollers within and adjacent to the collars E E, which receive the splintcrsor i'raying which are ot'ten found on the edges of the tire, and thereby cause it to tit more truly upon. thc rollers.

'Ihctire is bent by means of the roller D, which rests in bearingsin themorablc carriage F. This carriage slides on ways or guides ou the frame A, and is operated by means of a shaft, G, mounted in bearings in the ti-ame, and carrying two pinions, g g, which gear into racks ff, upon the carriage.

By rotating the shaft, byvmeans ot the crank g',

increment is readily and conveniently imparted to the carriage.

Having thus fully described my invention,

What I claim therein as new, and desire to secure by Letters Patent, is

1. In combination with a tire-bending machine, a. series of interchangeable collared rollers, as and for the purpose specified.

2. Forming grooves in the rollers adjacent to the collars, as and for the purpose specified.

3. 1n combination with the ti'ameA, the pivoted latch H, arched support I, and roller U, as and for the purpose specified. i

4. In combination with the frame A, and rollers'B and G, the carriage F, r; oki ff, pinions g g, and shaft G, as and t'or tlxelmrposc specitied. A Witnesses: y, JOHN NAUGLE.
